"That man is the product of causes which had no prevision of the end they
were achieving; that his origin, his growth, his hopes and fears, his loves
and his beliefs, are but the outcome of accidental collocations of atoms; that
no fire, no heroism, no intensity of thought and feeling can preserve an
individual life beyond the grave; that all the labors of the ages, all the
devotion, all the inspirations, all the noonday brightness of human genius,
are destined to extinction in the vast death of the solar system, and that the
temple of Man's achievement must inevitably be buried beneath the debris of
the universe in ruins-all these things, if not beyond dispute, are yet so
nearly certain, that no philosophy which rejects them can hope to stand. Only
within the scaffolding of these truths, only on the firm foundation of
unyielding despair can the soul's habitation henceforth be safely built."
